    Hi I was wandering if there is a way of dividing and/or multiplying frequencies by 100 or even 1000?
    I couldn't find anything on google in that range.

    As i don't have a pic programmer i cant make something with a pic (that i suspect would solve my problem)
    I need it to make my own frequency counter and frequency generator using picaxe

    If you're not concerned by the waveform, division can be done using a divider.

    You could also investigate PLLs.

    What do you need this for? There may be an easier solution.

    Thanks Steve, for division i don't need the waveform to be identical i only need it to give an accurate and steady number of pulses i don't care how much it alters the waveform and even the duty cycle.

    For the multiplier i need it to be as accurate as possible, maintaining waveform and duty (of course i am ok if it changes sine wave to square.)

    Edit: just looked for the PLLs seems fine for me (if you tell me how to wire it of course :) )

    Here is an application sheet for the popular 4046 PLL.
